Hypertensive ECG t-wave flattening can be caused by overexertion, myocardial ischemia, and pulmonary embolism. Overexertion causes may resolve spontaneously, others usually do not.
1. Overexertion: Transient hypertension and ECG t-wave usually appear after staying up late, anxiety, or excessive fatigue, usually without any physical symptoms, and other auxiliary examinations are not problematic, and usually get better after resting.
2. Myocardial ischemia: if there is a history of hypertension, diabetes mellitus, in addition to smoking, alcohol and other risk factors, ECG T-wave flattening changes may be a manifestation of myocardial ischemia, in addition to chest pain, chest tightness, panic and other physical symptoms, this time it may be an organic lesion, and will not be cured by itself.
3. Pulmonary embolism: long-term bed-ridden patients with little lower limb activity, chest tightness, dyspnea and other growths, ECG anterior wall T-wave flattening, and there are signs of increased load on the right heart, may be a pulmonary thromboembolism, which will not be self-cured at this time.
Note that it should be seen promptly for a thorough examination.
